New Waste Tank Pickup Tube
OMG!--a manufacturing defect on a Grand Banks! Just kidding; this is the best-built boat I have ever owned. But, the 25-gallon heavy-duty plastic holding tank on my 1990 GB 32 (#834) WAS built with an internal pickup tube made of metal which completely corroded after 29 years. Only a couple of gallons of waste would come out before the pump started sucking air. The top of the tank is just a few inches below the cabin sole so, to replace it, I first had to cut a hole in the cabin sole (under the drawers behind the helm seat, fortunately), remove the metal flange holding the tube and vent, build a new one out of PVC, and replace. Of course, I replaced and re-sealed the sole cutout, so no new noise, heat, or fumes gets into the cabin. All in all, not that hard a job, and the PVC should last forever. If you want more details, feel free to PM me.
